burning problem

[urfa]

Until now I did not have any problem to burn any kind of softwares or files. I used Clone CD 4 and easy cd creator. Rcently Clone Cd 4 refuse to burn any disc for a roblem with the laser calibration? Easy cd creator also gave me the same problem.
I have reinstalled Win98 se and Clone CD 4 and nero burning 5.5. I have removed easy cd creator. No difference, Nero burning tell me that the burning is successfull, but actually the disc remain blank!
My cd writer is HP 8200
Do you have any idea? Some helps will be the wellcome.
Thank you
